An animal shelter in Philadelphia recently took in two eight-month-old pit bull brothers named Jeffrey and Jermaine, and quickly realized Jeffrey was BLIND. But he got around okay, because Jermaine has learned to act as his SEEING-EYE dog.

Basically, Jeffrey walks behind Jermaine with his head resting on his back, and Jermaine just goes about his business. But when they're separated, they freak out.

So the shelter realized they had to find someone willing to adopt BOTH dogs, which is normally pretty tough, especially when one has special needs. So last week, they posted a photo of the two dogs sleeping together, with their ARMS around each other.

And the photo was so touching, that in two days, Jeffrey and Jermaine's adoption page got over THREE MILLION hits . . . with people from all over the WORLD trying to adopt them.

The shelter stopped accepting applications on Tuesday, because so many people had applied. Now they're sifting through candidates to find the best match. But they want to remind people that there are a lot of OTHER dogs out there who still need a home.
